It-has already been proposed to wind up tops by rotating their peg along bars which are toothed or act by friction. It has more particularly been proposed to cause such a rack to en- 5 gage with the pinion of a pin provided with a thread, which was screwed into a top peg having the form of a screw nut,l so that the top, put in` rotation by pulling the rack, was released by screwing out'of the pin.

According to the present invention a dancing disc, which is provided with a supporting or spinning peg having a channel threaded aperture extending through thedisc into the peg for thev reception of a drill spindle'and serving as a support for the top, is put in rotation by the relative displacement of two suitably shaped bars which are pressed against one another by spring liressure.` On the bars coming suddenlyto rest the top which with its peg in the form of a drill spindie is screwed into the said female thread will nevertheless seek to continue to rotate, so that it will lift itself out of the said thread and will `continue to dance on the said dancing disc or on the floor.

The arrangement according to the 'invention is shown in Figs. 1 to 6 diagrammatically in one constructional form by wayof example. Figs.'1 and 2 show one of the winding up bars from-the inside and outside. Figs. 3 and 4 show the as# sociated bars seen from above in the initial and the final position. Fig. 5 shows the top with the dancing'dise in side elevation, partly in section. ainsi Fig. 6 a plan view of the top and the dancing As shown, the two bars consist of the handle 1 'and the actual bar 2. .The latter has on its inside a recess which occupies about a. third of its length and which is formed at its ends, at 3- near the handle and at 4 near the fre'e end of the bar by 40 notches which are almost half as deep as the thickness of the tcp peg. For th rest the recess represents approximately a convex Acurve'which -in the middle-at 5- touches the original surface of the bar. The bars are also providedwith a 'slot 6 which extends from the inside to the outside and does not reach the ends of the bar. The bars are held together with their inner surfaces'in contact with one another by weak resilient means. The arrangement hereinafter described has been found to be particularly suitable forfthis purpose. A U-shaped wire stirrup 'l isinserted near the Vfree en'd of each bar at 8 in such a manner' that \`the middle'partof the stirrup is adapted to slide ,in the slot 6 provided in the other bar. The foot end of the stirrup which projects through the said slot carries a cap-9 between which and the outer surface of the bar resilient means 10 are provided, which press the bars together.

On the two bars being slid together,- so that the notches 4 are opposite one another, the peg 11 of the top can be introduced into the channel thus formed. On the bars beingpulled apart,.

the peg will move to the two other `notches 3 and will in the meantime by travelling' over the surfaces 5 be put in very rapid rotation. If, as shown in Fig. 5, the peg has its other screwed end 12 in the internally threadedfoot piece 13 of the dancing disk 14, the top 15 will as already stated lift itself out of the said disc and will continue to dance-either on the disc or on the iioor.

The advantage of the present inventionas compared with the'known art consists more particularly in this, that after cessation of the driving.

-force derived from the winding up device ,(Figs.

1-4), 'the gyratory force Iof vthe top'is converted into an increased rotary speed, so that it will rotate more rapidly than `corresponds to the original speed of rotation of the dancing disc. 'The top will thus be screwed out of the lower part by virtue of its increased rotary speed. It is obvious that when it is screwed -out the .top will make a lateral movement and will'further rotate either on the disc'14`or more probably on the iioor. Y

What I claim is:

1. A spinning topA toy comprising in combination a top comprising an axial pin, a lower spinning part having a dancing disc, an axial internal thread in the said lower spinning part, a

Athread on the lower part of the said axial pin,

adapted to engage in the said internal thread, and means for' imparting a 'rotary motion to the top, whereby, after the force causing the rotary motion has ceased, the rotating top can screw itself out vof the lower spinning part. I

2. A spinning top toy comprising in combination a top having a pin threaded at its lower por.-

vtion, a detachable lowerpart having a. threaded aperture, the two threaded parts operating freely together.l and the direction of rotation to detach or connect the two parts being in the same plane as-the rotation 'of the top when spinning whereby a diii'erence in speed of rotation o f the two parts of the toy detaches the top from the lower part,
